The reactivity of 2-alkylidene-imidazolidines 2 in inverse Diels-Alder syntheses with several pyridazines and 1,2,4-triazines is compared with that of acyclic ketene acetals 1. The 2-cyclopropylidene-imidazolidine 2~ is particularly suited for less reactive dienes. Extensive work of Sauer 1) and ot

Asymmetric inductive effects have been measured on the Diels-Alder reaction of dimethyl fumarate with o-quinodimethane bearing a chiral u-alkoxy group. The chiral substituents used were f-phenylethoxy, 2-(1-phenyl)propoxy, 1-(2\_phenyl)propoxy, 2-(4-phenyljbutoxy and l-cyclohexylethoxy. The greatest
